Topic Last Modified: 2015-10-15

This is an old version of the topic. To see the current version, change the (v=exchg.150) value in the URL to (v=exchg.160).

This cmdlet is available only in Exchange Online Protection.

Use the Remove-EOPDistributionGroup cmdlet to delete distribution groups or mail-enabled security groups in Microsoft Exchange Online Protection (EOP) standalone. This cmdlet isn't available in Exchange Enterprise CAL with Services (EOP Premium). In EOP Premium, use the Remove-DistributionGroup cmdlet.

Typically, EOP standalone customers that also have on-premises Active Directory organizations would use directory synchronization to create users and groups in EOP. However, if you can’t use directory synchronization, then you can use cmdlets to create and manage users and groups in EOP.
This cmdlet uses a batch processing method that results in a propagation delay of a few minutes before the results of the cmdlet are visible.

For information about the parameter sets in the Syntax section below, see Syntax.

Remove-EOPDistributionGroup [-ExternalDirectoryObjectId <String>] [-Identity <DistributionGroupIdParameter>] [-Organization <OrganizationIdParameter>]

This example removes the existing Exchange Online Protection distribution group named Security Team.

Remove-EOPDistributionGroup -Identity "Security Team"
